Improvement in boring artesian wells



UNITED STATES PATENT OFFICE.

DANIEL WHEELER, OF DECOEAH, IOWA.

IMPROVEMENT IN BORING ARTESIAN WELLS.

Specification forming part of Letters Patent No. 53,7ll5, dated April 3,1866.

To all 'whom it may concern:

Be it known that I, DANIEL WHEELER, of Decorah, in the county ofWinnesheik and State of Iowa, have invented a new and useful Improvementin the Machine for Boring Artesian Vells 5 and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation ot' the same, reference being had to theannexed drawings, making a part of this specification, in which- Figures1, 2, and 3 are detached parts, showing the nature of my improvement.Fig. 4 is a perspective view ofthe whole machine.

This invention relates, irst, to an improved mode of unwinding oruncoiling the rope to which the drill-rod is suspended as the drillpierces the' rock; second, automatically turning the drill at eachstroke, which in other boring-machines is now done by hand; third, adrill with its cutting-edge so shaped as to more effectually pierce therock.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The ratchet-wheel B, Fig. 1, is attached to the end of the roller onwhich the rope H His wound. The catch A, Fig. l, which works in theratchet-wheel, prevents the rope from unwinding. The rope H H passesaround auother roller, E, Fig. 1, and from thence up over the derrick K,Fig. 4, to the drill-rod X A, Fig. 4, the rollers B and E and catch A,Fig. 1, being attached to lever A A, Fig. 4, and as the stirrup B B,Fig. 4, revolves it presses the lever A A down, and by means of the roperaises the drill. As the stirrup passes on it relieves the lever andallows the weight ofthe drill and rods to draw it up. As the drill worksinto the rock the rope raises the lever farther until the upper endofthe catch A, Fig. 1, strikes the stop F, Figs. 1 and 4, thus raisingthe lower end of catch and allowing the ratchet-wheel to turn one cog,thus unwinding the rope, when the action of spring C C, Fig. 1,immediately draws the catch back again.

A N, Fig. 3, represent a metal cog-wheel with a square hole through itscenter, through which the drill-rod works up and down. The dog C, Fig.3, has its end at D attached to the top ot the axle on which the lever AA, Fig. 4, works, and which is also a part of said lever. As the leveris pressed down by the stirrup B B, Fig. 4, the dog C, Fig. 3, is drawnso as to turn the cog-wheel one cog, thus turning the drill, while thestationary dog F F, held by its spring G, Fig. 3, holds the cogwheclstationary till the next revolution of the machine.

X A, Fig. 2, represent the drill with its square rod A C attached. G B,Fig. 2, repreresent the improved shape of the cutting-edge ot' drill.

As drills are commonly made the cuttingedge radiates from the center otthe drill, thus cutting` in nearly parallel lines, while this drill,being shaped as shown at C B, Fig. 2, possesses cutting-edges which worknearly at right angles, or cross-cuts its work, thus more effectuallyreducing the surface ot' the rock.

Vhat I claim as lmy invention, and desire to secure by Letters Patent,is-

1. The combination of stop F, catch A, and ratchet B, in combinationwith rollers B and E or any equivalent contrivauce, workingsubstantially as described.

2. The cog-wheel AN, with the square hole A B for the drill-rod to Workin, iu combination with the moving dog C, stop-dog F F, and spring E,connected with dog C, or an equivalent contrivance, workingsubstantially as described.

DANIEL WHEELER.
